Uséeste códigoen uno demis últimosproyectos:
function ng_get_excerpt( $count ){ $permalink = get_permalink( $post->ID ); $excerpt = get_the_content(); $excerpt = strip_tags( $excerpt ); $excerpt = mb_substr( $excerpt, 0, $count ); $excerpt = mb_substr( $excerpt, 0, strripos( $excerpt, " " ) ); $excerpt = rtrim( $excerpt, ",.;:- _!$&#" ); $excerpt = $excerpt . '<a href="'.$permalink.'" style="text-decoration: none;"> (...)</a>'; return $excerpt; }
Lo obtuve desde aquí:
http://wordpress.org/support/topic/limit -extracto-longitud-por-caracteres
Tiene la ventaja denopermitirpuntuación alfinal yterminar con la últimapalabra completa
Usar losfiltros como sugiere @medhamza7 o @bainternet o @fuxia espreferible.
I used this code in one of my last projects:
function ng_get_excerpt( $count ){ $permalink = get_permalink( $post->ID ); $excerpt = get_the_content(); $excerpt = strip_tags( $excerpt ); $excerpt = mb_substr( $excerpt, 0, $count ); $excerpt = mb_substr( $excerpt, 0, strripos( $excerpt, " " ) ); $excerpt = rtrim( $excerpt, ",.;:- _!$&#" ); $excerpt = $excerpt . '<a href="'.$permalink.'" style="text-decoration: none;"> (...)</a>'; return $excerpt; }
I got it from here:
http://wordpress.org/support/topic/limit-excerpt-length-by-characters
It has the advantage of not allowing punctuation on the end and ending with the last complete word
Using the filters as suggested by @medhamza7 or @bainternet or @fuxia is preferable.

@Marcin [`substr ()` se romperá] (http://wpengineer.com/2410/dont-use-strlen/).Nunca lo useen datos codificadosen UTF-8.@Marcin [`substr()` will break](http://wpengineer.com/2410/dont-use-strlen/). Never use it on UTF-8 encoded data.

Utilice lafunción
utf8_truncate()
deesta respuesta y ábrasepasowp_trim_excerpt()
.Código demuestra,noprobado:
add_filter( 'excerpt_more', 'wpse_69436_excerpt_more' ); function wpse_69436_excerpt_more( $more ) { add_filter( 'wp_trim_excerpt', 'wpse_69436_trim_excerpt' ); // we remove the more text here return ''; } function wpse_69436_trim_excerpt( $excerpt ) { return utf8_truncate( $excerpt, 300 ); }
Use the function
utf8_truncate()
from this answer and fight your way throughwp_trim_excerpt()
.Sample code, not tested:
add_filter( 'excerpt_more', 'wpse_69436_excerpt_more' ); function wpse_69436_excerpt_more( $more ) { add_filter( 'wp_trim_excerpt', 'wpse_69436_trim_excerpt' ); // we remove the more text here return ''; } function wpse_69436_trim_excerpt( $excerpt ) { return utf8_truncate( $excerpt, 300 ); }

WordPresstiene unfiltropara lo que se llama convenientementeexcerpt_length y acepta varios caracteres,así que:
function custom_excerpt_length( $length ) { return 50; } add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );
cambie 50 al límite que desee.
Actualizaciónpor comentario de @toscho:
esaes la solución anteriortambiénesparapalabras ynopara caracteres,así que aquí hay una rápida:
add_filter('the_excerpt','excerpt_char_limit'); function excerpt_char_limit($e){ return substr($e,0,50); }
WordPress has a filter for that which is conveniently named excerpt_length and it accepts a number of chars so:
function custom_excerpt_length( $length ) { return 50; } add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );
change 50 to whatever limit you want.
Update per @toscho comment:
that is the solution above is for words as well and not for chars so here is a quick one:
add_filter('the_excerpt','excerpt_char_limit'); function excerpt_char_limit($e){ return substr($e,0,50); }

Esonoesparapersonajes,esparapalabras.That’s not for characters, it is for words.

Para unamejormanera,puede utilizarelfiltro
get_the_excerpt
:function get_excerpt($excerpt="",$limit=140){ $excerpt = preg_replace(" (\[.*?\])",'',$excerpt); $excerpt = strip_shortcodes($excerpt); $excerpt = strip_tags($excerpt); $excerpt = mb_substr($excerpt, 0, $limit); $excerpt = mb_substr($excerpt, 0, strripos($excerpt, " ")); $excerpt = trim(preg_replace( '/\s+/', ' ', $excerpt)); $excerpt = $excerpt.'...'; return $excerpt; } add_filter('get_the_excerpt',"get_excerpt");
Cambie
$limit=140
por la cantidad de caracteres que desee. También si quieres de otraforma:add_filter('get_the_excerpt',function ($excerpt="",$limit=140){ $excerpt = preg_replace(" (\[.*?\])",'',$excerpt); $excerpt = strip_shortcodes($excerpt); $excerpt = strip_tags($excerpt); $excerpt = mb_substr($excerpt, 0, $limit); $excerpt = mb_substr($excerpt, 0, strripos($excerpt, " ")); $excerpt = trim(preg_replace( '/\s+/', ' ', $excerpt)); $excerpt = $excerpt.'...'; return $excerpt; });
Esoevitará cualquier conflicto comoelnombreexistente de lafunción
get_excerpt
.For a better way, you can use the
get_the_excerpt
filter:function get_excerpt($excerpt="",$limit=140){ $excerpt = preg_replace(" (\[.*?\])",'',$excerpt); $excerpt = strip_shortcodes($excerpt); $excerpt = strip_tags($excerpt); $excerpt = mb_substr($excerpt, 0, $limit); $excerpt = mb_substr($excerpt, 0, strripos($excerpt, " ")); $excerpt = trim(preg_replace( '/\s+/', ' ', $excerpt)); $excerpt = $excerpt.'...'; return $excerpt; } add_filter('get_the_excerpt',"get_excerpt");
Change the
$limit=140
to the number of characters you want. Also if you want in different way:add_filter('get_the_excerpt',function ($excerpt="",$limit=140){ $excerpt = preg_replace(" (\[.*?\])",'',$excerpt); $excerpt = strip_shortcodes($excerpt); $excerpt = strip_tags($excerpt); $excerpt = mb_substr($excerpt, 0, $limit); $excerpt = mb_substr($excerpt, 0, strripos($excerpt, " ")); $excerpt = trim(preg_replace( '/\s+/', ' ', $excerpt)); $excerpt = $excerpt.'...'; return $excerpt; });
That will make avoid any conflict like existing name of function
get_excerpt
.-
@Nicolai creo que deberíamosevitar usar `mb_substr`porque algunas configuraciones dephppor defectono activan lasfuncionesmb:/@Nicolai i think we should avoid using `mb_substr` cause some php config by default doesn't activated mb functions :/

Como se lee [aquí] (https://wordpress.stackexchange.com/a/11089/22534),WPtiene una alternativa.As read [here](https://wordpress.stackexchange.com/a/11089/22534), WP has a fallback for it.
